CAR-COUPLING.

SPEGIFICATION forming part of Letters IPatent N 0. 743,169, datedNovember 3, 1903.

Original application filed September 27, 1902, Serial No. 125,092.Divided and this application filed August 20, 1903. Serial No. 170,169.(No model.)

To ctZZ whom it may concern:

Be it known that I, STEPHEN E. JA0KMAN, a citizen of the United States,and a resident of the city of New York, Coney Island, borough ofBrooklyn, in the county of Kings and State of New York, have invented anew and Improved Car-Coupler, of which the following is a full, clear,and exact descriptiomthis being a division of the application forLetters Patent of the United States, Serial No. 125,092, filed by meSeptember 27, 1902.

The invention relates to amusement devices, such as inclined orswitch-back railways; and its object is to provide a new and improvedcar-coupler for convenient and safe coupling of the cars and arranged toprevent coupled cars from jumping upward ofi the track, especially whenrunning over steep inclined portions in the track of the railway.

The invention consists of novel features and parts and combinations ofthesame, as will be more fully described hereinafter and then pointedout in the claims.

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure 1 is a side elevation of the improvement, showing two carscoupled together. Fig. 2 is a plan view of the same. Fig. 3 is anenlarged side of the improvement as applied and showing the car-axles insections; and Fig. 4 is a like view of the same, showing the parts in adifierent position.

Each of the cars B B is provided with a longitudinally-extendingdraw-barO, fulcrumed at O in the truck-frame and extending over a guide-plate Bbeyond the end of the car, as shown in the drawings. The outward end ofthe draw-bar is connected by a transverse pivot O with a coupling-link 0having a lug or projection O at each end, adapted to swing in engagementwith the top of the draw-bar O to prevent the coupled cars from jumpingupward off the track-rails. On the end of each car and directly over thedraw-bar O is arranged a bracket 0 to prevent the projecting end of adraw-bar from being bent upward on an unusual strain.

By reference to Fig. 1 it will be seen that the bottom edges of the lugs0 stand normally at angles to the top surfaces of the draw-bars O toallow the adjacent coupled cars to readily travel over portions of thetrack curved in a vertical plane; but in case a rear car should undulypress a forward car, then the draw-bar of the rear car causes an upwardswinging of the connecting-link on the other draw-bar as a fulcrum untilthe lug abuts against the draw-bar of the forward car, thus holding thiscar down and preventing further upward swinging of the connectinglink,so that the following car cannot leave the track. (See Fig. 4.)

By having the draw-bars mounted to swing on vertically-disposed pivots,as shown, the cars are free to readily travel around sharp curvesdisposed in a horizontal plane without undue binding of the couplingmembers. Having thus described my invention, I

claim as new and desire to secure by-Letters' Patent- 1. A car-couplingcomprising a longitudinal draw-bar pivoted on the car, to allow thedraw-bar to swing sidewise, a coupling-link pivoted on the draw-bar andarranged to swing up and down, and a lug on the coupling-link, adaptedto engage the top ofthe draw-bar, to prevent thecar from swinging up, asset forth.

2. A car-couplingcomprising a longitudinal draw-bar pivoted on the car,to allow the draw-bar to swing sidewise, a coupling-link.

provided on the draw-bar and arranged to swing up and down, a lug on thecouplinglink, adapted to engage the top of the drawbar, to prevent thecar from swinging up, and a fixed stop on the car, over that portion ofthe draw-bar projecting beyond the car, as set forth.

3. A car-coupler comprising longitudinal draw-bars pivoted on the carsand mounted to swing in a horizontal plane, and a coupling-linkpivotally connecting the free ends of the draw-bars with each other, thecoupling-link being capable of swinging in a vertical direction, as setforth.

4, A car-coupler comprising longitudinal draw-bars pivoted on the carsand adapted to swingin a horizontal plane, a couplinglink pivotallyconnecting the free ends of the draw-bars with each other, thec0up1ing-1ink being capable of swinging in a vertical direction, andlugs on the ends of the couplinglink, for engagement with the draw-bars,as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

STEPHEN E. J ACKMAN.
